fail-over firewall causing packet loss

LionKin1984 — Tue, 12 Mar 2019 07:18:20 GMT

Guys

As the title suggested, we have two ASA5510 firewalls running fail-over (active-standby), however we have been experiencing packet loss (2 ping drops every minutes) for traffic traversing the firewalls (between multiple servers), however when we switch off the standby firewall then everything starts working as intended (no more packet loss).

any ideas?

I am going to take a running-config for both firewalls and do a compare and see if anything obvious can be spotted

thanks

Hi,

Did you check from Physical layer end? Any errors accumulating on firewall interfaces when you ping across while on the packet loss path?

Thx

Hi mvsheik123

thanks for your reply

I haven't checked the physical layer yet, but if it was layer 2 that was causing the issue wouldn't the ping drop be random? instead of 2 packed loss every minute?

no errors on interfaces either.
